- Title
Beef cows with atypical estrous cyclicity at puberty produced calves with deficits in preweaning muscling, metabolic indicators, and myoblast function but not in feedlot performance.

- Abstract
The article tests the hypothesis that additional weight at weaning in their offspring is due to muscling and growth efficiency, characterized by better myoblast function, lean mass and metabolic efficiency. The growth and metabolic parameters in calves prior to weaning and in the feedlot are evaluated, along with carcass characteristics at harvest. Calves from cows that have typical pubertal cyclicity, start-stop pubertal cyclicity or noncyclic puberty are compared.
